The new layout columns component can be used to customize the page layout by adding additional columns into the main layout areas.
The new column component works with the existing page layouts by adding additional columns into the main section areas. You can use this component to create a layout that has 4 columns across the top, with 3 columns in the middle of the page and 4 columns at the bottom. Within each column, you can move components up and down. Currently, there is not an option to move components between each of the columns. Find out more about this feature here...
